exFAT

exFAT (Extended File Allocation Table), a Microsoft file system optimized for flash memory storage such as USB sticks, is available to Gentoo Linux systems through a FUSE module.

NoteThe availability of the exFAT filesystem had long been poor, because of its proprietary, unpublished specification. The situation, however, may change, following the publication of the spec by Microsoft in 2019. In kernel 5.7, released in Jun 2020, Linux kernel itself implemented an exFAT driver.
